I have lost 1 large cayuga duck, and 3 average size chickens in 3 days. Apparantly, whatever i am battling, drags the chickens up on to my barn Roof to eat them!! It goes into a well enclosed cage, and ripped a hole in my Gamebird Netting and is dragging my birds out!! I have a hunting camera set up, and this thing is faster than the camera. Will a weasel do this??
